Chrysanthemum plant named ‘White Yomistique’

ABSTRACT

A new  Chrysanthemum  plant named ‘White Yomistique,’ particularly distinguished by the small single white ray florets, compact and short, uniform habit with excellent branching, and dark, glossy small foliage.

Latin name of the genus and species of the plant claimed: Chrysanthemum×morifolium.

Varietal denomination: ‘White Yomistique’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new Chrysanthemum, botanically known as Chrysanthemum×morifolium, and hereinafter referred to by the variety name ‘White Yomistique’.

The new cultivar has small single white ray florets, compact and short, uniform habit with excellent branching and dark, glossy small foliage.

‘White Yomistique’ is a product of a planned breeding program. ‘White Yomistique’ originates as a natural whole plant mutation of ‘Frosty Yomistique,’ U.S. Plant Pat. No. 20,224. ‘White Yomistique’ was discovered and selected by the inventor as a single flowering plant within a population of the parent cultivar, grown outdoors in a field covered by saran in Fort Myers, Fla., in February, 2007. The parent cultivar ‘Frosty Yomistique’ has white with a slight pink hue flower color and lighter foliage color.

The first act of asexual reproduction of ‘White Yomistique’ was accomplished when vegetative cuttings were propagated from the initial selection in May 2007 in a controlled environment in Fort Myers, Fla.

Horticultural examination of plants grown from cuttings of the plant initiated in May 2007, and continuing thereafter, has demonstrated that the combination of characteristics as herein disclosed for ‘White Yomistique’ are firmly fixed and are retained through successive generations of asexual reproduction. ‘White Yomistique’ has not been observed under all possible environmental conditions. The phenotype may vary significantly with variations in environment such as temperature, light intensity and day length.

A Plant Breeder's Right for this cultivar was applied for in Canada in October 2008. ‘White Yomistique’ has not been made publicly available more than one year prior to the filing of this application.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographic drawing shows typical flower and growth habit characteristics of ‘White Yomistique’ with colors being as true as possible with an illustration of this type.

The photographic drawing shows 3 flowering potted plants of the new variety, with a close-up of the flowers.

DETAILED BOTANICAL DESCRIPTION

The plant descriptions, measurements and aforementioned photographs were taken in Gilroy, Calif. in May 2009 under greenhouse conditions. The plants were started and grown in central coastal California, then shipped to Gilroy, Calif. in April 2009. Plants were grown under conditions which approximate those generally used in commercial potted Chrysanthemum production and were about 9-10 weeks of age.

Color references are made to The Royal Horticultural Society Colour Chart (R.H.S.) 2001.

BRIEF SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be basic characteristics of the new variety. The combination of these characteristics distinguishes this Chrysanthemum as a new and distinct variety.
